And for the possibility of Atletico Madrid taking advantage when Barcelona and Real Madrid are inconsistent, of course it is very large, but the Atletico Madrid team must also be able to maintain consistent performance and be able to appear stronger.
If we look at the strength, I think Atletico Madrid this season is not as good as Barcelona or Real Madrid.
What has happened so far this season does not determine what will happen. Barça had also started very strongly and look at the last few games. I'm certainly glad that Atletico Madrid are in a position to challenge the other two for the league, and in the last 11 seasons they have been the only team to win two leagues, apart from Barcelona and Madrid.
If we recall the expectations from the season and compare them with what we have now, I think many will agree that Real is performing below expectations, Barcelona is above, and Atletico is at par (slightly behind both main contenders).
It would be logical to assume that Real, having dealt with injuries, will rise to the expected level, Barcelona will not hold outperforming for a long distance and Atletico will continue in its style. But bookmakers think differently and underestimate Real in my opinion.
